1728 THE BUTTERFLIES OF NEAV ENGLAJJD. 



fnscated. Length of body, l.S mm. ; width, .-t mm. ; of head, .50 mm. ; length of long 

 hairs, .33 mm. 



Second stage (80: CO). Mr. Fletcher tells me that the body is yellowish, the last 

 abdominal segment darker from the reddish brown pile. 



Third stage. Head (80 : 61) black with short, inconspicuous, whitish hairs ; lirst tho- 

 racic segment almost covered by an unbroken, equal, dorsal shield from just above the 

 spiracles on one side to the same point on the other. Body pale brownish yellow with 

 a dull greenish tinge above, and an exceedingly faint, dusky, laterostigmatal line; 

 whole body heavily and uniformly flecked with blackish brown dots, formed of the little 

 warts. Length, 4 ram. ; breadth of head and body, .85 mm. 



Fourth stage (77 : 27). Head (80 : 62) black, minutely and uniformly but irregularly 

 punctuate, covered with very short, delicate, pale brown hairs ; mouth parts and an- 

 tennae all black. Body dull olivaceo-griseous, darker al)ove than below, flecked all 

 over with minute, brownish fuscous dots in a pale annulus, each emitting a hair like 

 those on the head ; an indistinct, slender, dusky, medio-dorsal line and on the abdominal 

 segments a similar infrastigmatal line; flrst thoracic segment pallid with a pretty 

 broad, equal, piceous shield reaching from just above the spiracle to the same point 

 on the other side ; prolegs concolorous with body ; legs blackish fuscous ; spiracles 

 black ; the last segment of the body broadly bordered with a fuscous baud and pro- 

 vided also with a similar medio-dorsal stripe ; a scarcely discernible, dusky, lateral band. 

 Length (in early part of stage) 8 mm. ; breadth, 1.5 mm. 



Last stage (77 : 35). Head black, coarsely punctured and pubescent. Body rich 

 purplish brown with a green tinge, showing through the transparent skin; thoracic 

 shield black and shining, the rest of the first thoracic segment milk white above; sur- 

 face of body finely mottled with gray and dark purplish brown, and, like the head and 

 thoracic shield, covered with a fine, short, black pubescence ; contractions of dorsal 

 vessel plainly visible, giving the appearance of a dark brown dorsal stripe, ending 

 posteriorly in a blackish triangle, on each side of which are two small, laterodorsal, 

 black, comma-like dashes, running backward half way to the exterior margin of the 

 anal plate which is black above, whitish beneath. Thoracic legs and spiracles black, 

 the posterior pair, with the markings on the anal plate, giving the appearance of a bear's 

 face. Length, 25 mm. (After Fletcher.) 



Chrysalis (85 : 44) . Head and prothorax black, together with the legs and antennae ; 

 wings at flrst green, afterwards greenish black; meso-and metathorax brown, the 

 former edged posteriorly with blackisli fuscous ; the abdomen light brown with 

 slight and minute infuscations ; the whole body with sparsely scattered, ferruginous 

 papillae, annulate at base with black or fuscous, supporting moderately long, tapering, 

 pointed, straiglit or arcuate, pallid hairs which are more or less tufted at the extreme 

 front and on either side of the ocellar ribbon, those at the front of the body more or 

 less fulvous, those upon the abdominal segments longer, as long as the segments, sub- 

 recumbent, directed backward; cremaster luteo-testaceous, edged with fusco-casta- 

 neous ; booklets castaneous. Surface everywhere very delicately vermiculate. Length of 

 body, 13 mm. ; of cremaster, 1.3 mm. ; width of head, 3.25 mm. ; of mesothorax, 3.85 

 mm. ; of abdomen at third abdominal segment, 4.35 mm. From a specimen sent by 

 Mr. Fletcher, aided by his notes. 



Distribution ( 32: 3). This butterfly is found over perhaps a larger 

 extent of" territory than any other species t)f the tribe. A member princi- 

 pally of the Alleghanian fauna, it appears also to occur in nearly the whole 

 of both the Canadian fauna to tlie north and the Carolinian to the south. 

 Excepting specimens brought from Florida by Mr. Maynard, the southern- 

 most examples have occurred in the west at Dallas, Texas (Boll), and in 

 the east in Virginia (Coll. Amer. ent. soc.), Delaware (the same), and 

 Louisville, Ky. (Belknap, Mus. Yale Coll. ) . To the west it occurs abund-
